.To a/ZZ whom t may concern:

Beit known that we, THOMAS KNoWLEs, cotton-spinner, of No. 287 BlackburnRoad, Bolton, in the county of Lancaster, and ROGER TATHAM,machine-maker, of Rochdale, in the said county, England, have inventedcertain new and useful Improvements Applicable to Oarding-Engines inwhich R evolving Flats are Employed, (for which We have obtained BritishPatent No. 2,912, dated February 27, 1888,) of which the following is aspeciiication.

Our invention relates to those carding-engines in which revolving iiatsare employed; and our invention consists in 'arrangements of apparatusfor grinding the flats em ployedk in such'carding-engines.

For the purpose of our invention We cause the ,back7 of each end of theiiat about to be ground77 to travel along an inclined sur face and passbetween the inclined surface and a fixed guide. Each of the inclinedsurfaces and iixed guides is mounted upon or connected in any suitablemanner to one of the bends or side frames, or any other suitable part ofthe carding-engine, so as to be capable of being adjusted in position.

For convenience of description we shall hereinafter in vmany instancesonly refer to theapparatus situate at one side of the carding-engine,although the arrangements of apparatus in Which our invention consistsand the apparatus used in conjunction with our invention are, in so faras may be necessary, applied alike to each side of the carding-engine. v

In the accompanying drawings, Figure l is a front view, and Fig. 2 aside view, showing so much of a carding-engine as is requisite toillustrate our invention. Figs. 3 and 4 are diagrams, on a larger scale,illustrative of certain details of the working ot' our invention.

The same letters of reference are applied to corresponding parts in allof the gures.

Secured to the bend of the carding-engine is a bracket a. To aprojection a', formed upon the bracket a, is secured the curved bracketb, along the upper edge b of which the revolving iiats c travel whenaway from the main cylinder of the carding-engine.

i Mounted upon the bracket ct and secured thereto by the bolts d2 andnuts cl3 is a bracket e. The said bracket e is formed with a part e',the lower edge of which is formed with two surfaces e2 es, connected byan inclinedy surface e4.

Secured to the bracket a by the nut f is a studf, mounted upon which andfree to be turned thereon is a lever g, one end g 0f which is formedwith a flat or nearly-dat surface g2, extending from A to B, andinclined surfaces g8 g4. The other end of the lever g is provided with aweight g5, which tends to turn the end g of the lever g in the directionindicated by the arrow O. In place of the weight g5, a spring or otherequivalent for such weight g5 may be employed.

Mounted upon the bracket a, and secured thereto by means of the bolt dand nut d', is a bracket h, which supports, so that it may be turnedtherein, one end of the axle j of the grinding-rollcrj.u The bracket his provided with screws and nuts, by means of which the grinding-rollercan be adjusted' into the required position; but as such screws and nutsare similar to those ordinarily in use for similar purposes we haveomitted them from the drawings in order to avoid confusion. One end ofeach of the flats c while away from the main cylinder of thecardingengine passes between the end g of the lever g and thebracket e.

c c2 c3 are flats. The iiat c is about to be ground. The iat c2 is beingground by the grinding-roller j, and the dat c3 has been ground. Themotion of each of the flats c in the direction indicated by the arrow Dcauses,

each of such Hats c to pass beneath the grinding-roller j. The' portionof each of the flats c which at times is against the surfaces I e2 e* e3of the bracket e is that portion c4 of the fiat c which is supportedbythe iiexible bend or other bend when the said flat c is at work.7 Themovement of the flats c in the direction indicated by the arrow D willcause the portion c5 of each of such ilats c to travel along theinclined surface g4.and the surface g2 of the lever g. The weight gswillcause the end c6 of the flat c to be pressed against the surfaces e2 e3of the bracket. The movement of the tiat c in the direction indicated bythe arrow D will cause the edge 'c7 of the fiat c to pass along thesurface e3 and the edge c8 to travel along the surface e2. While theedge c7 is traveling along the surface e3, and while the edge o8 issupported on the su rface e2, the Wire surface c9 of the Hat c will beoperated upon bythe grinding-rollerj,which is caused to rotate in themanner in which grinding-rollers are ordinarily caused to rotate.

Fig. 3 is a detached view showing, upon a larger scale, thegrinding-roller j and a section of a iat c being ground, the surfaces e2e3 and inclined surface e4 being shown detached in order thatconfusionmaybe avoided. The surface c3 is formed at such a height above thesurface e2 that when the edge c7 of the flat c is traveling along thesurface e3 and the edge es of the flat c is traveling along the surfacee2 the fiat @will be tilted in the direction indicated by the arrowT E,so that the surface F F of the Hat c will be parallel to Vthe surface e2and the surface e3, and that the card-wire surface c9 of the flat cwillbe ground parallel to the surface F F of the ilat c, to which thecard-wire a9 is attached. After the wire e9 of the flat c has beenoperated upon by the grinding-rollerj a continued movement of the flatcin the direction indicated by the arrow D will carry the flat c clearot' the surfaces e2 e3 and the surface g2 upon the lever g. By causingthe edges c7 @sof each flat c to travel along the surfaces e2 e3 whilethe flat c is being ground, We insure that the Wire of all the flatsshall be ground uniformly in relation to the surfaces by which suchflats are heeled when at Work.

The diagram Fig. 4 shows on a larger scale the advancing edge of a fiatas being about to commence to pass along the inclined surface e4, andindicates the mannerin which the part c10 of the card-clothing of a flatwhich may from any cause be too near the advancing edge of the tlat ormay project too much from the foundation of such card-clothing will beground so as to be brought into the condition requisite for properworking and so that it will not comeinto contactwith the card-surface ofthe main cylinder to agreater extent than the corresponding portion ofeach of the other flats. It will be seen from Fig.

4.- that before the edge c7 of the flat c commences to pass along theinclined surface e4 the angle 010 of the card-clothing upon the saidflat c will, it' it is too near to the advancing edge of the iiat orprojects too far from such fiat c, come into contact with thegrinding-rollerj and receive a grinding and be ground down to therequired extent. As soon as the edge c7 of the fiat ccommences to passalong the inclined surface e4 further contact between the card-surfaceof the dat c and the grinding-roller j will not take place until theedge c7 of the flat c arrives in contact With the surface c3. The anglec10 of the cardsurface of the dat c will thus be ground at an angle tothe remainder of such card-surface.

The amount of cardingsurface to be presented to the main cylinder by theflats operated upon by the grinding-roller may be regulated by theextent to which the angle cl0 of the flat isl ground by thegrinding-roller being varied. The extent to which the angle 010 of theflat is ground may be varied by the relative positions of the inclinedsurface c4 of the bracket e, and the point of contact between the anglec1@ of the VHat and the grinding-roller j being varied by the bracket eor the grinding-roller being moved in the direction indicated by thearrow G or in the direction opposite thereto into the required position.

If desired, special means for facilitating the movement of the grindingroller j or bracket c may be provided.

l-Iaving fully described our invention, what We claim, and desirev tosecure by Letters Patent, is-

The hereinbefore-described arrangements of apparatus for grinding theflats employed in carding-engines in which revolving iiats are employed,which arrangements of apparatus consist in fixed parts provided withsurfaces e2 and e3, formed parallel with each other and separated fromeach other by a diference of level such that a flat held against thesurfaces e2 and e3 will have its card-Wire surface parallel to saidsurfaces e2 and e3 and in levers, such as g, by means of which the flatsbeing ground may be successively held against the surfaces e2 e3, andarranged, employed, and operating in conjunction With a grinding-roller,substantially as and for the purposes hereinbefore described.
